Can anyone nail down why my car is squeaking when I hit the accelerator???

Not sure if Accufab is one of the aftermarket ones that whistle (Fox guys could probably answer that one), but some of them do with how the air passes over the blade. I've heard the PP ones do, but mine's quiet. You could put a piece of hose to your ear and listen around the engine bay to try to figure out where it's coming from. May just be a cracked vacuum line or something, too. You recently swapped the stroker in, right? Could've bumped something that took a little time to open up and start making noise. The vac lines get rock hard and brittle from the heat.
 
Keith, normally the air out the front seal is when the PCV is used but that oil-filler to CAI tube is removed. Since you have a couple of breathers, you should be ok. If it makes the noise while idling in your garage, you can remove the oil filler cap and see if the noise suddenly goes away. If so, you're on the right track. If the noise persists, it should not be a crankcase ventillation issue.

BTW, it sounds like you did good. You either want a nice closed PCV system (like OEM) or completely ditch that and run breathers. No mixing and matching though, as it can cause a lean condition with unmetered air.

Good luck bud.
